Such a mating contact may have parallel elongated members on which the mating surface are positioned, providing for the possibility of more than two contact surface per mating contact portion. The mating contact surfaces may be positioned on the elongated members such that the points of contact are at different distances from the distal end of the mating contact portion.

An angled circuit board connector includes a unitary connector block having first and second board-contacting faces. The first and second board-contacting faces are arranged relative to each other at an operative angle. The connector block includes a block body. The first and second board-contacting faces face outward from the block body. A first connector port is located on the first board-contacting face. A second connector port is located on the second board-contacting face. A connector trace extends through at least a portion of the block body between the first and second board-contacting faces. The connector trace electrically connects the first and second connector ports.

Systems and methods are described for transmitting data over physical channels to provide a high bandwidth, low latency interface between a transmitting device and a receiving device operating at high speed with low power utilization. Communication is performed using group signaling over sets of four wires using a vector signaling code, where each wire of a set carries a low-swing signal that may take on one of four signal values. Topologies and designs of wire sets are disclosed with preferred characteristics for group signaling communications.

A retention apparatus for a shielded cable is described. In one embodiment, the apparatus comprises a substrate having a ground; a connector coupled to the substrate; a cable shielded with a conductive material and having an end connectable to the connector to electrically connect with the connector; an electrically conductive material coupled to the ground of the substrate; and a grounding retention mechanism to cause the electrically conductive material to electrically connect the cable to the ground of the substrate by applying a force to the cable shield.

An example port protector includes a plug housing including an exterior surface and an interior surface, the plug housing sized to mate with a data communication port of an electronic device. The port protector also includes an opening extending from the exterior surface to the interior surface. The port protector further includes a storage container disposed within the plug housing, the storage container to release an adhesive agent via the opening based on an interaction between the plug housing and the data communication port.

An electrical connector includes an insulative housing, a number of first contacts and second contacts, an insulator inset-molded with the first contacts, a metallic shielding plate retained in the insulative housing, and a shielding shell attached to the insulative housing. The housing has a base portion defining a receiving cavity located at a back-end thereof and extending forwardly and a tongue portion extending forwardly from the base portion. The tongue portion defines a first surface carrying the first contacts and a second surface located oppositely and a number of terminal-receiving slots located at the first surface and the second surface and communicated with receiving cavity. The second contacts are inserted into terminal-receiving slots located at the second surface. The insulator is received in the receiving cavity to insert the first contacts into the terminal-receiving slots located at the first surface.

A first case is integrally provided with a connection housing open to a side of the first case. A second case is integrally provided with a support base projecting toward the first case and facing inside the connection housing from a window provided in the connection housing. A bus bar included in a connection terminal disposed inside the connection housing is provided along the support base and is interposed between the support base and the first case, and is positioned in a projecting direction of the connection terminal.

The disclosure relates to a cable concentrator and an electronic device having the same, where the cable concentrator includes main body and ground partition plate. The main body includes sidewall portions and bottom plate portion together forming accommodation portion to accommodate cable connectors. The bottom plate portion has positive terminal holes and negative terminal holes. The ground partition plate is located in the accommodation portion and divides the accommodation portion. The ground partition plate has ground bent tabs respectively corresponding to the negative terminal holes of the bottom plate portion and are electrically connected to negative terminals on a circuit board and thus grounding the negative terminals.
